Abstract
A multilayer barrier structure includes a plurality of relatively thin nanocomposite layers separated by one or more relatively thick intermediate layers selected from synthetic elastomers or non-elastomeric polymers. The composites exhibit remarkably long breakthrough and lag-times and are useful for packaging or protective apparel.
